The page Compare Office 365 Business Plans shows you the Office 365 business plans. But it doesn't tells you which plan includes SharePoint Online. I know that Office 365 Business Premium does include SharePoint Online because I have the trial version.
So please tell me which Office 365 Business Plan include SharePoint Online.
EDIT: Perhaps "Team Sites" on this page refers to SharePoint Online?
EDIT: I found this blog post: Comparing features in SharePoint Online across Office 365 Service Plans. It is from May 2012, so it is a bit outdated. Plans have changed from Kiosk, Small Business and Enterprise to Business Essentials, Bussines and Bussines Premium. So I guess all Office 365 plans include SharePoint Online. Do you know a page with updated info on this?
